Powered by the merkaio Stack
The merkaio Stack
A modular offering built around one unified foundation.
merkaio core
The unified IoT foundation
A standardized, proven IoT technology stack - from devices to dashboards.
One stack. Fully understood. Fully operable.
merkaio ops
Operated IoT platforms
We operate the complete merkaio stack as a managed service.
You don't run the stack. We do.
merkaio cloud
Cloud foundation for IoT workloads
The secure and scalable infrastructure layer for IoT operations.
Cloud-native by design. Built for IoT realities.
merkaio dev
Custom extensions & integrations
When standard components are not enough, merkaio dev extends the stack - from decoders to complete IoT apps.
We extend the stack - we don't reinvent it.
Hardware Expertise with Milesight
We rely on Milesight and know the product portfolio inside out - from environmental sensors to LoRaWAN gateways to industrial controllers. We advise, source and integrate the right hardware for your use case.
We also work with hardware from other manufacturers - whether proprietary or open-source. What matters is that it works reliably and integrates into our stack.
We break the pattern.
Why pay for software that's actually free?
The IoT market is full of "proprietary platforms" that trap customers in expensive licensing models. Look under the hood, and you'll often find open-source technology (like ThingsBoard or Grafana) that's been relabeled. We think that's wrong. We play with open cards.
The Market Standard
The Trap- White-LabelingOpen-source software is sold as proprietary invention.
- License CostsYou pay high monthly fees per device for software that's actually license-free.
- Vendor Lock-inYour data and configurations are trapped in a "blackbox". Switching is nearly impossible.
- OpacityYou don't know what your business runs on.
The merkaio Way
The Solution- 100% TransparencyWe tell you exactly what we use (ChirpStack, ThingsBoard, Grafana).
- No License FeesYou pay for our work (setup, operations, security), not for the code.
- Full OwnershipThe stack belongs to you. You have full access to databases and admin panels.
- FreedomSince we use standards, you can theoretically take over operations yourself or switch providers at any time.
We don't hide behind licenses. We convince through operations.
